Stocks to watch on Tuesday:Glu Mobile (GLUU) - mobile-game developer closed near the low of the day with a minimal $0.09 gain. Stock probably needs to consolidate the gains at this point, but Glu Mobile remains cheap compared to the opportunity of the existing games and the potential of a Taylor Swift app. Synergy Pharma (SGYP) - predicted last week that the biotech would pull back. Just below $3, Synergy Pharma closes the gap and becomes a buy again. The market misses the Trulance sales and got too focused on the debt financing that remains a long-term positive. Twitter (TWTR) - the power of Twitter is proven every day. Engagement growth will lead to higher ad sales in 2018.
